A real-time rollover threat index for sports utility vehicles

The methodology capable of computing a time-to-rollover (TTR) index in real-time is verified by using test data of two sports-utility vehicles (SUV)-a 1988 Suzuki Samurai and a 1997 Jeep Cherokee. First, simple yaw-roll models are constructed based on the test data. The TTR is computed from the simple model and then corrected by using an artificial neural network. The TTR generated by the neural network is then verified against the data for the two test vehicles.
